FIELD OF THE DISCLOSURE

This patent generally pertains to flexible room dividers and, more specifically, to connector apparatus for wall panels.

BACKGROUND

Some room dividers include a series of semi-flexible curtains that are suspended from an overhead structure and are interconnected along their vertical edges by hook-and-loop fasteners. Some such room dividers provide a relatively quick, easy, and affordable way for separating interior spaces having different environmental requirements or for isolating spaces from dust, paint overspray, odors, and/or other airborne contaminants. In some examples, some room dividers include insulation to reduce heat migration within a building and to help maintain a desired air temperature and humidity within designated areas. Such areas, for example, may include areas used for storing refrigerated or frozen foods and/or other perishable goods.

Some room dividers are made of curtains having special qualities for certain purposes. For example, some curtains have acoustic insulation for noise absorption, impenetrable strength for security, and/or flame resistance for limiting the spread of smoke and/or fire.

DETAILED DESCRIPTION

Example room dividers disclosed herein include elongate connectors to interconnect and/or seal longitudinal edges of a plurality or series of insulated and/or otherwise padded curtains. Some example connectors disclosed herein have an S-shaped cross-sectional profile that establishes an overlapping joint at adjoining edges of the example curtains. In some examples, the example curtains employ hems folded over onto opposite faces of the curtain. In some such examples, the example connectors disclosed herein may employ a barb to engage at least a portion of an edge of the folded-over hem to help secure and/or hold a curtain in position. Some example curtains disclosed herein have a resiliently compressible core that expands to fill a pocket defined by the connector when the compressible core is coupled to the pocket of the connector. In particular, an expanded portion of the compressible core positioned within the pocket mechanically and/or frictionally holds the curtain engaged or coupled to the connector. To further ensure the integrity of a joint provided by the example connectors, some example connectors disclosed herein may employ a fastener that extends or passes through an example connector and/or overlapping edges of adjoining curtains. Some example connectors disclosed herein are support multiple curtains and/or attach the curtains to a building (e.g., a wall, a beam, and/or other structure).

FIGS. 1-14 illustrate example connectors 10 (e.g., connectors 10 a-j) to interconnect one or more curtains 12 (e.g., curtains 12 a, 12 b and 12 c) and/or to attach a curtain assembly to various building members 14 such as, for example, an overhead structure 14 a (e.g., ceiling, beam, truss, etc.), a wall 14 b, and/or a floor 14 c. Once installed, the curtain assembly can serve as a room divider 16, as shown for example in FIG. 1. FIG. 1 shows a variety of different curtains 12 and connectors 10 provided in a single curtain assembly. Other installations, however, would not necessarily have such variety at one location.

In the example of FIG. 1, a room divider 16 is shown having curtains 12 a 12 b, 12 d and 12 e. A connector 10 c of the illustrated example connects the adjoining (e.g., horizontal) edges of curtains 12 d and 12 e to provide a curtain assembly 12 c that is similar in size to curtains 12 a and 12 b. A connector 10 e of the illustrated example hangs curtains 12 a, 12 b and 12 c from an overhead structure 14 a, and a connector 10 g anchors the (e.g., lower) ends of curtains 12 a, 12 b and 12 c to floor 14. A connector 10 a joins the adjacent (e.g., vertical) edges of the curtains 12 a and 12 b, and a connector 10 b joins the (e.g., left vertical) edge of curtain 12 b to an adjacent (e.g., right) edge of curtain 12 c (e.g., in the orientation of FIG. 1). In the illustrated example of FIG. 1, the connector 10 b includes a plurality of connector segments 10 b′ distributed (e.g., vertically) along a substantially or entire (e.g., a full) height of the left edge of curtain 12 b. In some examples, the connector 10 a, the connector 10 b and/or connector 10 c has a cross-sectional profile similar to those shown in FIGS. 2-9. The connector 10 f of the illustrated example anchors the (e.g., right vertical) edge of the curtain 12 a to the wall 14 b. The cross-sectional profiles of the example connectors 10 a-i and their various mounting configurations are shown in FIGS. 2-14.

FIGS. 2-4 show an example sequence of using the connector 10 a to couple a left edge 18 of the curtain 12 a to a right edge 20 of the curtain 12 b. In this example, each of the curtains 12 a and 12 b includes a core sandwiched or positioned between two covers. More specifically, the curtain 12 a of the illustrated example includes a first core 22 sandwiched or positioned between a first front cover 24 and a first back cover 26. The curtain 12 b of the illustrated example includes a second core 28 sandwiched or positioned between a second front cover 30 and a second back cover 32.

The cores 22 and 28 provide the respective curtains 12 a and 12 b with characteristic(s) such as, for example, thermal insulation, fire resistance, sound absorption, and/or porosity. In some examples, porosity reduces weight, promotes compressibility, and/or increases thermal resistance. Thermal resistance is commonly quantified in terms of “R-value,” where higher R-values refer to structures (e.g., core, cover, etc.) having greater thermal resistance. Example core materials include, but are not limited to, batting, resiliently compressible foam, polyester fiber batting, carbon fiber batting, and/or fiberglass batting. Example nominal core thicknesses 34 include, but are not limited to, 0.25 inches, 0.5 inches, 0.75 inches, 1 inch, and 1.5 inches. To achieve such thicknesses, some core examples are single layer and some are multiple layers. For sound dampening, some example cores also include a mass loaded vinyl sheet (e.g., 1 lb/sqft).

The outer covers 24, 26, 30 and 32 help protect the respective cores 22 and 28 from wear, moisture, mold, mildew, and/or air borne contaminants. In some examples, the covers 24, 26, 30 and 32 of the illustrated example improve the appearance of the curtains and/or make the curtains easier to clean. In some examples, the covers 24, 26, 30 and 32 include a fire resistant vinyl fabric (e.g., 18 oz/sqyd, 0.032 in thick, 0.063 in thick, and/or other material weights or thicknesses). The core/cover assembly provided by the core 22 and the outer covers 24 and 26 provides the curtains 12 a with a nominal thickness 36 spanning from the outer cover 24 to the outer cover 26. Similarly, the core/cover assembly provided by the core 28 and the outer covers 30 and 32 provides the curtain 12 b with the nominal thickness 36 spanning from the outer cover 30 to the outer cover 32. Further, the curtain 12 a has an edge 18 that opposes the edge 20 of the curtain 12 b. The example edges 18 and 20 of the illustrated example are vertically elongate. In addition, the cores 22 and 28 are both softer and more compressible than the outer covers 24, 26, 30 and 32. Providing relatively softer cores 22 and 28 (e.g., softer than the covers 24 and 26 and/or softer than the connector 10 a) provides the respective curtains 12 a and 12 b with the compressibility to become pinched, indented, clamped, squeezed, deformed and/or otherwise compressed. As a result, the cores 22 and 28 enable the respective curtains 12 a and 12 b to be securely gripped by the connector 10 a. The covers 24, 26, 30 and 32 are also sufficiently pliable to be securely gripped by the connector 10 a. However, because the covers 24, 26, 30 and 32 are not as soft as the cores 22 and 28 provides the respective curtains 12 a and 12 b with strength and/or wear resistance. The term, “nominal thickness” (e.g., the thickness 36) as it pertains to a curtain (e.g., core plus covers) refers to the curtains average overall thickness excluding areas of the curtain that are compressed within a connector (e.g., the connector 10 a). The curtains 12 a and 12 b of the illustrated example each has a curtain height 38 extending between an upper edge 40 (FIG. 10) and a lower edge 42 (FIG. 12).

In some examples the core 22 and/or the core 28 of the respective curtains 12 a and 12 b may be thicker (e.g., between a face adjacent the respective covers 24 and 30 and a face adjacent the respective covers 26 and 32), may have a greater thermal resistance, and/or may be more porous than the covers 24, 26, 30 and/or 32 of the respective curtains 12 a and 12 b. The thickness of the core 22 and/or 28 being greater than the thickness of the covers 24, 26, 30 and/or 32 provides compressibility to enable the connector 10 a to grip the respective curtains 12 a and 12 b more securely and/or more firmly. The cores 22 and/or 28 being more porous than a porosity of the covers 24, 26, 30 and/or 32 provide the respective curtains 12 a and 12 b with a desired compressibility while retaining the curtain's wear resistance due to the characteristics and/or quality of the covers 24, 26, 30 and/or 32. Furthermore, the thermal resistance of the example cores 22 and 28 provides the respective curtains 12 a and 12 b with a relatively high R-value while retaining wear resistance due to the quality of the covers 24, 26, 30 and/or 32.

FIGS. 2-4 show the example connector 10 a having a connector width 44 and a connector thickness 46. FIG. 1 shows the example connector 10 a vertically elongate having a connector height 48 that is at least five times greater than the width 44 and at least ten times greater than the thickness 46. Such dimensions in addition to connector 10 a being harder and/or stiffer than the curtains 12 a and 12 b provide the connector 10 a with a compact profile while still being able to securely hold and seal along the edges 18 and 20 of the respective curtains 12 a and 12 b. Example connector 10 a materials include, but are not limited to, steel, aluminum, other metals, plastic, alloys and/or another material(s). Additionally, the example, the connectors 10 a-10 j can be made by various methods, examples of which include, but are not limited to, extruding, brake formed, and/or roll formed. It should be noted that the difference between the connector thickness 46 and a material thickness 50 of connector 10 a is that the connector thickness 46 is measured across the entire thickness of the connector 10 a (e.g., across a first outermost edge or face and a second outermost edge or face opposite the first outermost edge or face) while the material thickness 50 is measured across a base material of the connector 10 a. For example, the material thickness 50 is measured across a flange (e.g., a first flange 52, a second flange 54, or a web 56).

In the illustrated example, the connector 10 a the first flange 52, the second flange 54, the web 56, a first bend 58 and a second bend 60. The term, “bend” refers to a structure that is curved or angled with no regard as to how the bend was made. For example, a bend is not necessary created by bending material. The web 56 of the illustrated example lies or is positioned between the flanges 52 and 54 such that the web 56 and the two flanges 52 and 54 overlap each other. The web 56 extends widthwise between a first bend 58 and a second bend 60. The first bend 58 connects or couples the first flange 52 and the web 56 and the second bend 60 connects or couples the second flange 54 and the web 56. The first flange 52 of the illustrated example terminates at a first flange edge 62 that is vertically elongate and proximate the second bend 60 and/or the web 56. The second flange 54 of the illustrated example terminates at a second flange edge 64 that is vertically elongate and proximate the first bend 58 and/or the web 56. In some examples, the term, “proximate” refers to a distance that is less than the connector's thickness 46.

To couple the curtains 12 a and 12 b, the edge 18 of the curtain 12 a is inserted or positioned into a first pocket 66 defined by the first flange 52, the first bend 58 and the web 56 of the connector 10 a. Likewise, the edge 20 of the curtain 12 b is inserted into a second pocket 68 defined by the second flange 54, the second bend 60 and the web 56. Upon the insertion of the edge 18 of the curtain 12 a into the first pocket 66, the first outer cover 24 lies against or (e.g., directly) engages the web 56. The first core 22 of the illustrated example is compressed between the first flange 52 and the web 56 (and/or the second bend 60) to provide the first curtain 12 a with a first (e.g., localized) compressed thickness 70 that is less than the nominal thickness 36 of the first curtain 12 a. The indentation caused by the compression of the first core 22 helps hold the first curtain 12 a within first pocket 66. For example, compressing a portion of the core 22 at the edge 18 to the compressed thickness 70 increases a frictional force between the curtain 12 a and the connector 10 a when the edge 18 is inserted in the first pocket 66. Likewise, upon the insertion of the curtain 12 b into the second pocket 68, the second outer cover 30 lies against or (e.g., directly engages) the web 56. The second core 28 of the illustrated example is compressed between the second flange 54 and the web 56 (and/or the first bend 58) to provide the second curtain 12 b with a second (e.g., localized) compressed thickness 72 that is less than the nominal thickness 36 of the second curtain 12 b. The indentation caused by the compression of the second core 28 helps hold or secures the second curtain 12 b within the second pocket 68. For example, compressing a portion of the core 28 at the edge 20 to the compressed thickness 72 increases a frictional force between the curtain 12 b and the connector 10 a when the edge 20 is inserted in the second pocket 68 of the connector 10 a.

To further secure the curtains 12 a and 12 b to the connector 10 a, some examples connectors disclosed herein may employ a fastener (e.g., mechanical fastener, a chemical fastener, a pin, adhesive, etc.). For example, the connector 10 a of the illustrated example includes a fastener 74, such as a rivet 74 a (e.g., a blind rivet, a pop rivet, other types of rivets, etc.) and/or a threaded fastener 74 b (e.g., a self-tapping screw, a sheet metal screw, other types of screws, etc.). To simplify and/or facilitate installation of the curtains 12 a and 12 b with the connector 10 a, the fastener 74 can be installed via access to only one side of the curtains 12 a and 12 b (e.g., a side of the respective outer covers 24 and 30). In some examples, the connector 10 a includes a hole 76 and the curtains 12 a and 12 b (e.g., drilled through the connector 10 a in a direction of the thickness 46 as shown in FIG. 3).The fastener 74 can be inserted through the hole 76 such that the fastener 74 penetrates or passes through the first curtain 12 a, the second curtain 12 b, the web 56, the first flange 52 and the second flange 54, as shown in FIG. 4.

FIG. 4 illustrates the first curtain 12 a and the second curtain 12 b of the illustrated example coupled via the connector 10 a. In some examples, the localized indentation in the curtain 12 a at the first flange edge 62 and the similar indentation in the curtain 12 b at the second flange edge 64 create or provide a living hinge along each indentation (e.g., at the respective first and second flange edges 62 and 64). The living hinges allow the web 56 of the connector 10 a to tilt, cant and/or otherwise move slightly out of parallel alignment relative to the curtains 12 a and 12 b, thereby allowing the curtains 12 a and 12 b to lie or move in coplanar alignment with each other. Specifically, FIG. 4 shows the curtains 12 a and 12 b both lying along a common plane 78 while web 56 lies non-parallel or canted relative to the plane 78. For example, the compressed edge 18 of the curtain 12 a may be at an angle or non-parallel relative to the non-compressed portion of the core 22 and/or curtain 12 a. Similarly, the compressed edge 20 of the curtain 12 b may be at an angle or non-parallel relative to the non-compressed portion of the core 28 and/or the curtain 12 b. As a result, parallel faces (e.g., defined by the respective covers 24 and 30) of the example curtains 12 a and 12 b of the room divider 16 can appear to lie relatively flat from the curtain 12 a to the curtain 12 b.

FIGS. 5, 6 and 7 show examples of various connectors constructed in accordance with the teachings disclosed herein. FIG. 5 shows a connector/curtain assembly 80 similar to that shown in FIG. 4 but without the fastener 74. Without the fastener 74, the connector 10 b grips two curtains 12 b and 12 c by way of friction and/or a mechanical interlock created by the curtains 12 b and 12 c being thicker at their edges 82 than at compressed indentations 84 where the flange edges 62 and 64 of the connector 10 b pinch curtains 12 b and 12 c.

FIG. 6 shows a connector 10 c having flange edges 86 each including a barb 88 that engages a folded-over hem 90 at a curtain edge 92. In this example, a front cover 94 and a back cover 96 are folded over to create the hem 90. The hem 90 can be held in the folded-over state by any suitable fastening process(es), examples of which include, but are not limited to, sewing (e.g., a seam 98), ultrasonic welding, thermal welding, gluing, and/or other process(es). When using a plurality of connectors 10 c to interconnect the edges of a series of curtains, the two edge hems 90 of each curtain 12 b and 12 c may be folded over in opposite directions, (i.e., one forward and one back). For example, FIG. 6 shows the hem 90 of curtain 12 b folded toward an upward direction in the orientation of FIG. 6 and shows the hem 90 of the curtain 12 c folded toward a downward direction in the orientation of FIG. 6. In some examples, a hem-engaging barb 88′ is provided or formed on the flange edge 86 and/or on an opposing surface 87, as shown in FIGS. 15, 16 and 17. In some examples, a series of discrete barbs 88″ are stamped into a sheet metal connector 10 j, as shown in FIGS. 18 and 19. In some examples, barbs 88″ protrude so as to engage the hem 90 of a curtain (e.g., the curtain 12 c) along a series of contact points, while the remaining portion of the connector 10 j provides a continuous seal along the hem's length.

FIG. 7 shows another example connector 10 d constructed in accordance with the teachings of this disclosure. The connector 10 d of the illustrated example is made primarily of metal (e.g., aluminum, steel, brake formed, roll formed, extruded, etc.) with a polymeric coating 100 (e.g., vinyl, polyurethane, etc.) on at least one flange 102. The coating 100 provides a layer of thermal insulation that helps prevent frost from accumulating on the side of the connector 10 d that is facing warm ambient air 104 while the other side of the connector 10 d is facing a refrigerated area 106.

FIGS. 8 and 9 schematically illustrate profile or shape of a connector (e.g., connector 10 b of FIG. 5) that is representative of the connectors 10 a-10 d shown in FIGS. 2-7. For example, an example connector of the illustrated example of FIG. 8 has an S-shaped profile or cross-sectional shape. FIG. 8 shows the connector 10 b having a first surface 108 extending contiguously from the first flange edge 62, across the first flange 52, around the first bend 58, across the web 56, around the second bend 60, across the second flange 54 and to the second flange edge 64. FIG. 9 shows the example connector 10 b having a second surface 110 extending contiguously from the first flange edge 62, across the first flange 52, around the first bend 58, across the web 56, around the second bend 60, across the second flange 54 and to the second flange edge 64. When attached to the curtains 12 b and 12 c, as shown in FIG. 5, the curtain 12 c engages the first surface 108 and is spaced from the second surface 110, and the curtain 12 b engages the second surface 110 and is spaced from the first surface 108.

The example connector 10 e of FIG. 10 connects or couples the upper edge 40 of the curtain 12 b and the overhead structure 14 a. In this example, the connector 10 e is a seamless unitary piece or structure having a mounting flange 112, a first flange 114 and a second flange 116. In the illustrated example, the mounting flange 112 is substantially parallel to and/or coplanar with the second flange 116. The curtain's upper edge 40 fits within a pocket 118 (e.g., a channel) between the flanges 114 and 116, and the barb 88 engages the hem 90 to help secure the curtain 12 b. In some examples, the fastener 74 (not shown in FIG. 10) penetrates the flange 114, the flange 116 and the curtain 12 b to further help secure the curtain 12 b to the connector 10 e in a manner similar to that shown in FIGS. 3 and 4. In some examples, a fastener 120 anchors the mounting flange 112 to the overhead structure 14 a.

The connector 10 e of the illustrated example has an overall length 122 (FIG. 1), a width 124 and a thickness 12 b. In some examples, to avoid air or smoke passage between the curtain 12 b and the connector 10 e, the overall length 122 of the connector 10 e is substantially equal to or greater than the length of the upper edge 40 of the curtain 12 b. The term, “substantially equal to” as it pertains to the relative lengths of a connector and a curtain edge (running horizontally or vertically) means that the connector extends the (e.g., entire) full length of the curtain's edge (e.g., vertical edge or horizontal edge) less any relatively small clearance needed for connecting an adjacent connector at the end of the length. For example, in the room divider's upper right corner of FIG. 1, the connector 10 e stops just short of the curtain's uppermost right corner to make room for the adjacent connector 10 f at that corner. In some examples, the length or height of a curtain edge and the respective connector extend substantially vertically (e.g., connectors 10 a, 10 b, and 10 f), and in other examples, the length of a curtain edge and the respective connector extend substantially horizontally (e.g., connectors 10 c, 10 g, and 10 e).

FIG. 11 shows the example connector 10 f connected or coupled to a right edge 128 of the curtain 12 a and the wall 14 b. In this example, the connector 10 f is a seamless unitary piece or structure having a mounting flange 130, a first flange 132 and a second flange 134. In the illustrated example, the mounting flange 130 is substantially parallel to and/or coplanar with the second flange 134. The curtain's right edge 128 fits within a pocket 136 (e.g., a channel) between the flanges 132 and 134, and the barb 88 engages the hem 90 to help secure the curtain 12 a. In some examples, the fastener 74 (not shown in FIG. 11) penetrates the flange 132, the flange 134 and the curtain 12 a to further secure the curtain 12 a to the connector 10 f in a manner similar to that shown in FIGS. 3 and 4. In some examples, a fastener 138 anchors the mounting flange 130 to the wall 14 b.

The connector 10 f of the illustrated example has an overall length 140 (FIG. 1), a width 142 and a thickness 144. In some examples, to avoid air or smoke passage between the curtain 12 a and the connector 10 f, the overall length 140 of the example connector 10 f is substantially equal to or greater than the length of the right edge 128 of the curtain 12 a.

FIG. 12 shows the example connector 10 g connected or coupled to a lowermost edge 42 of the curtain 12 b and the floor 14 c. In this example, the connector 10 g is a seamless unitary piece or structure having a mounting flange 146, a first flange 148 and a second flange 150. In the illustrated example, the mounting flange 146 is substantially perpendicular relative to the second flange 150. The curtain's lower edge 42 fits within a pocket 152 (e.g., a channel) between the flanges 148 and 150, and the barb 88 engages the hem 90 to help secure the curtain 12 b. In some examples, the fastener 74 (not shown in FIG. 12) penetrates the flange 148, the flange 150 and the curtain 12 b to further secure the curtain 12 b to the connector 10 g in a manner similar to that shown in FIGS. 3 and 4. In some examples, the fastener 120 anchors the mounting flange 146 to the floor 14 c.

The connector 10 g of the illustrated example has an overall length 154 (FIG. 1), a width 156 and a thickness 158. In some examples, to avoid air or smoke passage between the curtain 12 b and the connector 10 g, the connector's overall length 154 is substantially equal to or greater than the length of the curtain's lower edge 42.

To achieve greater thermal insulation and/or sound absorption, some example room dividers disclosed herein have multiple curtain layers, as shown in FIGS. 13 and 14. In FIG. 13, the connector 10 h is connected or coupled to a first curtain 162 and a second curtain 164. The connector 10 h is a seamless unitary piece or structure having a mounting flange 166, a first flange 168, a second flange 170, and a third flange 172. In this example, the fastener 120 anchors the mounting flange 166 to the building member 14. A first edge 174 of first curtain 162 fits or is inserted within a pocket 176 (e.g., a channel) between the flanges 168 and 172, and the barb 88 engages the hem 90 to help secure the first curtain 162. Likewise, a second edge 178 of the second curtain 164 fits or is inserted within a pocket 80 (e.g., a channel) between the flanges 170 and 172, and the barb 88 engages the hem 90 to help secure the second curtain 164. In some examples, the fastener 74 (not shown in FIG. 13) penetrates the first curtain 162, the second curtain 164, and the flanges 168, 170 and 172 to further secure the curtains 162 and 164 to the connector 10 h in a manner similar to that shown in FIGS. 3 and 4.

In another multilayer curtain example, as shown for example in FIG. 14, the connector 10 i connects to a first curtain 162 and a second curtain 164.
